Answer:

The dolphin will jump 18 times in 2hours.  

Step-by-step explanation:

Find the jumps per hour: 54/6 = 9

^This means that the dolphin jumps 9 times in an hour.

9*2 (hours) = 18

The dolphin will jump 18 times in two hours.

The equation of the line that is parallel to the given line and passes through the point (-2,2) is:

y = \frac{x}{5} + \frac{12}{5}

<h3>What is a linear function?</h3>

A linear function is modeled by:

y = mx + b

In which:

  • m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.
  • b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.

When two lines are parallel, they have the same slope. In this problem, the given line passes through (-5,-4) and (0,-3), hence the slope is:

m = (-3 - (-4))/(0 - (-5)) = 1/5.

Hence the equation is:

y = \frac{x}{5} + b

When x = -2, y = 2, then:

y = \frac{x}{5} + b

2 = \frac{-2}{5} + b

b = \frac{12}{5}

Hence:

y = \frac{x}{5} + \frac{12}{5}

A line with a slope -2 passes through the point (-1,4). Which equation represents this line in point-slope form?
sesenic [268]

Answer:

  y-4 = -2(x+1)

Step-by-step explanation:

The point-slope equation of a line is ...

  y -k = m(x -h) . . . . . line with slope m through point (h, k)

You have m = -2 and (h, k) = (-1, 4). Putting these numbers into the above form gives ...

  y -4 = -2(x +1)
